(54)	Method and system for transmitting caller id information from a base station to a mobile unit outside the context of an incoming call

(57) A method for transmitting caller ID data from a base station to a mobile unit is provided that comprises receiving a call at a base station and receiving caller ID data associated with the call at the base station. The method then provides for storing the caller ID data at the base station and interrogating a mobile unit to determine reachability of the mobile unit. The method then provides for generating a mobile unit unreachable condition in response to the mobile unit not responding to the interrogation and the mobile unit reachable condition in response to the mobile unit responding to the interrogation. The method next provides for generating a mobile unit reachable condition when the mobile unit informs the base unit of its existence. The method next provides for establishing an air interface connection between the base station and the mobile unit in response to a transition from a mobile unit unreachable condition to a mobile unit reachable condition. The method finally provides for transmitting the caller ID data to the mobile unit when the air interface connection is established.
